CLAMPING OR SECURING DFVICE FOR KNIVES.

SPECIFICATION forming part of Letters Patent No. 526,292, datedSeptember 18, 1894.. Application filed A ri s, 1894. Serial No. 506,889.(No model.)

To all whom it may concern:

Beit known that I, HORACE S. BUOKLAND, of Fremont, in the county ofSandusky and State of Ohio, have invented certain new and usefulImprovements in Clamping or Securing Devices for Knives; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will whereby the blade is so firmly held within thehandle, ferrule or holder that it is not liable to become displaced orloose by use.

With this object in view, my invention con sists in certain features ofconstruction and incombinations of parts hereinafter described andpointed out in the claims.

Inthe accompanying drawings, Figure 1 is a side elevation showing myimproved means for securing a knife-blade within its handle orreceiving-ferrule or holder, the latter being shown partly in centrallongitudinal section. Fig. 2 is a top View relative to Fig. 1, partly incentral longitudinal section. Fig. 3 is a plan of a blank employed inthe formation of the clamping-device used to secure the knife-bladewithin the holder, handle or receiver. Fig. 4 is a side elevation,partly in section, showing the manner of assembling the parts. Figs. 5and 6 are side elevations, partly in section, illustrating a suitablemanner of securing the parts together.

Referring to the drawings, A designates a chambered handle, ferrule, orreceiving-shell or holder in which is introduced and suitably securedthe shank b of a working tool, such, for instance, as a cutting-blade,B. Blade B is shown suitably clamped against the interior surface of thehandle, shell, ferrule or holder A, and the clamping-device employed forthe purpose of securing member B in place is preferably of the followingconstruction.

The clamping-device is shown to consist of a single piece, preferably ofsheet metal, and

the blank 0 suitable for the formation of the clamping-device is shownin Fig. 3, the same consisting preferably of three members (0 O and 0arranged in line, as shown, the two end-members O 0 being substantiallythe same in construction and adapted, when bent laterally as hereinafterdescribed, to fit the handle, shell, ferrule or holder A internally. Theblank is bent into the shape shown in Figs. 4 and 5; that is, thecentral member or Web 0 of the blank, at two points located a suitableinterval apart, is bent laterally, as at O in the same direction onlines extending longitudinally of the blank, and the endmembers 0' Ci,at the junction of said members with the central member or connectingWeb, are bent laterally in the same direction so as to be capable ofbeing subsequently folded or pressed against the ends of thelaterally-bent portions of web or member 0 The end-members O G of theblank are also slotted laterally, as atC, with the slots extending fromthe central portion to the adjacent end of the blank and open at theirouter ends, as at 0 (See Fig. 3.)

The blank having been formed and bent into the shape hereinbeforedescribed, the shank of the cutting-blade or working-tool and the bentblank are introduced into the handle, shell, ferrule or holder A towhich the blade or working-tool is to be secured with the shank of saidtool engaging the lateral slots in the end-members of the blank, asshown in Figs. 4 and 5, and the end-members are thereupon, by means ofsuitable devices, pressed laterally against the stop-formingmembers 0formed upon the central member or web of the blank or clamping-device,thereby completing the clamping-device and bringing the end-members ofthe clampingdevice into a vertical position, and causing the shank ofthe cutting-blade or workingtool to be pressed or clamped outwardlyagainst the interior surface of the handle, fer- ICC cutting-blade orworking-member of the tool into engagement with the adjacent end-memberof the clamping-device, as shown in Fig. 5, and thereupon by means of aplunger E introduced into the opposite end of the handle, ferrule orreceiving-shell and brought into engagement with the other end-member ofthe clamping-device, forcing the clamping device endwise against theplug until the clamping-members of the clamping-device have been broughtinto engagement with the wings or stops formed upon the central memberor web of the clamping-device.

What I claim is- 1. A clamping-device for securing a knifeblade orworking-member of a tool into a hollow or chambered handle, ferrule orshell, consisting of two clamping-members located a suitable intervalapart, said clamping-members straddling the shank of the knife-blade ormember to be secured and clamping the same against the interior surfaceof the handle, ferrule or shell, substantially as set forth.

2. A clamping-device, for securing a knifeblade or working-member of atool into a hollow or chambered handle, ferrule or shell consisting oftwo members located a suitable interval apart and adapted to fit thehandle, ferrule or shell internally, said members being slotted tostraddle the shank of the knifeblade or the member to be secured andclamp the same against the interior surface of the handle, ferrule orshell, substantially as set forth.

3. A clamping-device for securing a knifeblade or working-member of atool within a handle, ferrule or holder, consisting of twoclamping-members located a suitable interval apart and slotted or cut toreceive the blade or working-member of the tool, and suitable means forholding said securing-members apart, substantially as set forth.

4; A clamping-device for securing a knifeblade or working-member of atool' within a handle, ferrule or holder, consisting of twoclamping-members located a suitable interval apart, said membersstraddling or embracing the blade or working-member of the tool andsecuring the same within the handle, ferrule or holder, saidsecuring-members being conneeted by a web and the latter being bent tobe engaged by the opposing sides of the securing-members, substantiallyas and for the purpose set forth.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 14th day of February, 1894.

HORACE S. BUCKLAND.
